Black hole spin cranks-up radio volume Posted: 12 Jan 2018 06:59 AM PST Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets. |
X-ray navigation could open up new frontiers for robotic spacecraft Posted: 11 Jan 2018 07:39 PM PST In a technology first, a team of engineers has demonstrated fully autonomous X-ray navigation in space -- a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond. |
Archeology of our Milky Way's ancient hub Posted: 11 Jan 2018 01:29 PM PST A new analysis of about 10,000 normal Sun-like stars in the Milky Way's bulge reveals that our galaxy’s hub is a dynamic environment of variously aged stars zipping around at different speeds. |
Swarm of hydrogen clouds flying away from center of the Milky Way Posted: 10 Jan 2018 01:32 PM PST Astronomers have discovered what appears to be a grand exodus of more than 100 hydrogen clouds streaming away from the center of the Milky Way and heading into intergalactic space. |
